Borealis

Install Borealis on Android

For phones and tablets with Android 7 or later and a 64-bit ARM (arm64) processor. Borealis is not on Google Play yet, so you install the APK file yourself.

Download Borealis_1.4.0_arm64.apk

Install

  1. On the phone, download Borealis_1.4.0_arm64.apk and open it, from the browser's downloads or the Files app.
  2. Android asks whether the app you opened it from (your browser or Files) may install apps. Allow it in the settings screen it shows, then go back.
  3. Tap Install, then Open.

The wording of these screens differs between phone makers and Android versions. Android asks only the first time for each app you install from.

Update

Download the new APK and install it the same way. It replaces the old version and keeps your characters, content and settings, because every release is signed with the same certificate.

Check the signing certificate

On a computer with the Android SDK build tools, run:

apksigner verify --print-certs Borealis_1.4.0_arm64.apk

The SHA-256 digest of the certificate must be:

42:A7:E1:F7:3D:85:F9:FC:28:A9:C5:E0:29:F8:C6:EC:CC:C6:E7:15:13:F5:5F:F3:A3:85:EF:D1:E2:D6:0C:2C

On the phone

The phone app has the same characters, content and rules as the desktop app. The tab bar at the bottom holds Start, Build, Magic, Gear, Play and More. The optional AI assistant is desktop only. To bring characters over from a computer, see Move characters between devices.
